Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Abstract

The common apartment or condominium has thin walls and ceilings that do not dampen audio transmissions very well, resulting in many noise complaints when the upstairs neighbor plays the stereo too loud. The source of the problem is the transmission of audio pressure/vibration waves from the speakers to the wall or the floor.

RATION DAMPING SYSTEM

Invention by: Paul Jaynes

The common apartment or condominium has thin walls and
ceilings that do not dampen audio transmissions very well, resulting in many
noise complaints when the upstairs neighbor plays the stereo too loud. The
source of the problem is the transmission of audio pressure/vibration waves
from the speakers to the wall or the floor.

To solve the problem of noise transmission, this invention
introduces a false speaker base composed of a series of rubber gaskets filled
with audio dampening material, possibly gel. The speaker vibration would be
partially damped by the gaskets through dissipating the energy with the gel
motion and the rubber's counteracting motion. The theory of this gasket system
can be thought of as a shock absorber for mechanical vibrations that are
produced by the airflow in a speaker.

The "Best Mode" would have to be determined by
vibration analysis. The design and form of the gasket, and the elasticity and
viscosity of the rubber and gel respectively, would 011 have to be determined
by experimentation. Without the use of computerized vibration analysis
software, it would take a very long time to find the best material and design
for this dampening system. If vibration analysis software is used to facilitate
this experimentation, optimization is likely to be achieved.
